A submarine began at sea level and descended toward the ocean floor at a rate of -0.015 km per minute. Its final depth was -0.3675 km. Estimate how long it took the submarine to reach its final depth by rounding the dividend and divisor to the nearest hundredth.

Estimate of the dividend: B. -0.37

Estimate of the divisor: D. 0.2

Estimate of the quotient: B. 5.67

Thats wrong and I need to get the right answer on the second try

Apologies for the incorrect response. Let's try again.

Estimate of the dividend: A. -0.38

Estimate of the divisor: D. 0.2

Estimate of the quotient: C. 1.85

To estimate the time it took for the submarine to reach its final depth, we need to divide the change in depth (-0.3675 km) by the rate of descent (-0.015 km per minute).

First, let's estimate the dividend. The given final depth is -0.3675 km. Rounding it to the nearest hundredth, we get -0.37. Therefore, the estimate of the dividend is B. -0.37.

Next, let's estimate the divisor. The given rate is -0.015 km per minute. Rounding it to the nearest hundredth, we get -0.02. Therefore, the estimate of the divisor is A. -0.02.

Finally, let's divide the estimated dividend (-0.37) by the estimated divisor (-0.02) to find the estimate of the quotient.

-0.37 ÷ -0.02 = 18.5

Rounding it to the nearest tenth, we get 18.5. Therefore, the estimate of the quotient is C. 18.5.

Hence, the submarine took an estimated 18.5 minutes to reach its final depth.
